Earth Science Weather Term Study Guide 1. Atmosphere—a mixture of gases that surrounds a planet 2. Atmospheric Pressure—the force per unit area that is exerted on a surface by the weight of the atmosphere. 3. Trophosphere—the lowest layer of the atmosphere in which the temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist 4. Statosphere—the layer of the atmosphere that lies between the troposphere and the mesosphere and in which the temperature increases as altitude increases (contains the ozone layer) 5. Mesosphere—the coldest layer of the atmosphere between the stratosphere and the thermosphere in which the temperature decreases as altitude increases 6. Thermosphere—the uppermost layer of the atmosphere in which the temperature increases (includes ionosphere) 7. Greenhouse Effect—the warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and reradiate infrared radiation 8. Dew Point—at constant pressure and water vapor content, the temperature at which the rate of condensation equals the rate of evaporation 9. Clouds—clouds form if the air cools to below its dew point Types of Clouds: Stratus Clouds—a gray cloud that has a flat, uniform base and that commonly forms at very low altitudes Cumulus Clouds—a low level, billowy cloud that commonly has a top that resembles cotton balls and a dark bottom Cirrus Clouds—a feathery cloud that is composed of ice crystals and that has the highest altitude of any cloud in the sky 10. Precipitation—any form of water that falls to Earth’s surface from the clouds; includes rain, snow, sleet, and hail 11. Cold Front—the front edge of a moving mass of cold air that pushes beneath a warmer air mass like a wedge 12. Warm Front—the front edge of advancing warm air that replaces colder air with warmer air 13. Stationary Front—a front of air masses that moves either very slowly or not at all. 14. Occluded Front—a front that forms when a cold air mass overtakes a warm air mass and lifts it off the ground and over another air mass. 15. Thunderstorm—a heavy storm that is accompanied by rain, thunder, lightning, and strong winds. 16. Hurricane—a severe storm that develops over tropical oceans and whose strong winds of more than 120 km/h spiral in toward the intensely low-pressure storm center. 17. Tornado—a destructive, rotating column of air that has very high wind speeds and that maybe visible as a funnelshaped cloud. 18. Wind Vane—an instrument used to determine direction of the wind 19. Station Model—a pattern of meteorological symbols that represents the weather at a particular observing station and that is recorded on a weather map.
